Sometimes the light will stay on for 100-500 miles depending on the fault code. You can disconnect the battery to reset it, but you will have to reset the radio and other memory such as seats mirrors.

    I found this on another site after looking for the same solution

    1. With your car OFF, place your key in the ignition and turn to "On". Do not start the car.
    2. Find the odometer button and press until it reads the total odometer setting, (not the Trip A or Trip B setting).
    3. Turn the key to OFF.
    4. Place your finger back on the odometer button, press and hold. At the same time, turn the key back to "On".
    5. Hold the odometer button in until the MAINT REQD light goes out...should take about 8-10 seconds.

2006 lexus es330 track off VSC plus the engine light is on

The ES330 has a notoriously bad fuel cap problem. Notice that if you tighten the cap two clicks it will come off with one finger. They apparently have a different cap not just a new cap. It will cause the Check Eng light to come on but apparently may also affect the VSC because it affects engine performance. When the VSC light comes on it will also shut down Trac Control and turn on the light. Replace the fuel cap! Cheap first fix. If you need to clear codes when you get the cap at Autozone they'll scan it and clear codes.

Check engine light came on ,when wife didn't turn gas cap three clicks ,how do i get it to go out

It can take a while for that to go away, If it was not the gas cap then it wont go away, autozone could have cleared the code and it would have gone away. You can clear the code by removing the fuse for the ecm or unhooking the battery, otherwise it may take 3 to 7 starting cycles to reset.

Trac off, check engine light and vsc lights on on a 2006 lexus es330

Hello, the reason for the vsc light to turn on is that the check engine light came on first causing the vsc system to become disabled, this is normal, once the cause of the check engine light is fixed the other lights will turn off. You'll need to find out the diagnostic codes that caused the check engine light to turn on first, most auto parts stores like autozone, pep boys, o reilly can help you with getting those codes from the computer and they do this for free in most US states, when you have the code numbers you can reply if necessary and I can advise as to what should be done.

99 lexus es 300 chk engine and trac lock lite on

I had check engine light and TRAC OFF. OBD-II MIL code was P1133 which is Air Fuel Ratio Sensor Response Malfunction and scanned by AutoZone. After disconnecting the battery for 10-15 minutes, the lights went off. I cleaned the gas cap and tightened it firmly. For the last 400 miles, the lights have not come back. When scanning using Snap-on one, no code was detected. I think gas cap was the reason for the lights.

2001 Lexus LS 430 the VSC off light and check engine warning light remains on

Apparently, the most common cause is a loose gas tank cap. It has to be tightened until it clicks. Other, more serious faults can cause this indication, but the loose cap issue is widespread. Hopefully, that's all it is in your case!
